BATTERY Application filed ma 19 The present invention is directed to improvementsin devices for protecting battery connections.

An object of the invention is to provide a device of this character constructed in such a manner that it can be easily and quickly applied to the post of a battery and when in place thereon will reduce .the corrosion of parts due to vapors arising from the battery to a minimum.

A further object of the invention is to provide a device of this character in which the post to which the lead in connection is secured is remote from the vent opening of the battery.v

With these and other objects in view, as will appear as the description proceeds, the

' invention consists in the novel features of a construction, combinations of parts hereinafter to be fully described and claimed.

In the accompanying drawing: Figure 1 is a top plan View of a portion of a storage battery having the deviceof my invention secured thereon,

Figure 2 is a vertical sectional view taken I on the line 22'of Figure 1,

Figure 3 is a vertical sectional view taken on the line 33 of Figure 1, and

Figure 4; is a perspective View of the device. M r

Referring to the drawing in detail, in which like reference numerals refer to like parts throughout the several views. i

1 designates a conventional form of bat: ery provided with the usual negative and positive posts 2 and 3, respectively.

Adapted to be fixed to the post 3 is an arm 4, said a'rm having an opening 5 in its inner end for receiving the post 3. This arm when in place is horizontally disposed and spaced from the top of the battery 1 and has its outer end provided ,with an integral vertically extending post6 to which is clamped the usual connector 7 to which the lead wire 8 is'c'onnected;

It will be. observed that when the arm 4- is in place "moisttire and vapors which may collect upon' post 3 and causes corrosion, will .be largely prevented from reaching the post 6, consequently eliminating corrosion at this point. It will be 'observed that should moisture collect upon the post 3 the likeli- TERMINAL.

7 hood of the same passing to the post 6 is small owing to the presence of the shoulder 9 formedby the lower surface. of the inner end of said arm. Any moisture which does collect upon the lower surface of the arm will by gravity drop therefrom and consequently will not reach the post 6 and connector 7, thereby eliminating possibility of corrosion. I

To secure the arm to the post 3 it is only necessary to apply the flame from a blow torch to cause parts of the post 3 and arm 4 to fuse. Thus the best possible permanent contact of the parts is obtained in such a way as to reduce corrosion to a minimum.

The connection of the post 6:and the connector 7 must be released, and remade many times in the life of a battery and means must be provided for assuring a good clean contact therebetween.

- For this purpose the cup 10 is provided inthe post 6 and has small openings 11 communicating therewith and passing to theouter surface of the post 6.

Inmaking the connection itis first assured that the interior of the connector and the exterior of post 6 are thoroughly clean, the cup 10 is filled, preferably with Vaseline or cup grease and when the connector is secured tightly in place suflicient of the vaseline is forced through aperturesll to collect I in a film between the post and connector to eliminate corrosion and thereby insure a good contact. The pressure of afinger on the top of the-filled cup serves to force the Vaseline through the aperture 11-.

What is claimed is: y

A terminal attachment for storage bat. teries comprising an arm having a tapered bore adapted to be fixed 'upona correspondingly tapered terminal of a storage battery, a tapered most arising from one end of said arm and disposed in offsetv relation with respect to said terminal, the diameter'and taper of said post being the same as that of said bore, said post being adapted to deta'chably receive a leadiconnector and to maintain said connecter spaced from said battery terminal.

In testimony whereof I aflix my signature.
